中风是美国第三大死亡原因。本研究的目的是通过实时听觉反馈的上肢运动轨迹修正来促进慢性脑卒中患者的运动恢复。一个系统的硬件，软件和反馈算法的开发。两组慢性中风期的患者接受了该系统的训练，一组进行了实践和反馈，另一组仅进行了实践。定义了20个到达参数，并分析了第一次和最后一次训练之间、适应和学习试验之间以及三个目标之间的差异。这项研究表明，在慢性中风期间，无论是通过单独的练习，还是通过伴随听觉反馈的练习，都可以完成伸展轨迹的修改。然而，改善的路径性能需要听觉反馈训练，并且不能仅通过练习来实现。
Stroke is the third leading cause of death in the United States. The aim of the present study was to enhance the motor recovery of patients in the chronic stroke period by means of upper extremity trajectory modification through real-time auditory feedback. A system of hardware, software, and feedback algorithms was developed. Two groups of patients in the chronic stroke period were trained on the system, one with practice and feedback and one with practice alone. Twenty reach parameters were defined and analyzed for differences between the first and last training sessions, between adaptation and learning trials, and among three targets. This study demonstrated that modification of the reach trajectory can be accomplished during the chronic stroke period either with practice alone or through practice accompanied by auditory feedback. However, improved path performance requires auditory feedback training, and cannot be achieved by practice alone.
